The NAB Show is being held at the Las Vegas Convention Centre from April 24-27, with a focus on digital audio and how technology is changing the shapes and sizes of sound equipment.
NUGEN Audio will unveil Halo Downmix, an all-new product for precise downmixing of feature-film or 5.1 mixes to stereo. Pre-existing tools can generate excess ambient sound as the rear channels collapse to stereo, and they can cause indistinct dialogue or disproportionate levels of low-frequency energy, the company says.
Original archive material, when upmixed using legacy methods such as rear-channel delay and phase shifting, can end up with audible timing errors when summed to the phantom centre. Halo Downmix surmounts these challenges by giving the engineer hands-on control over the relative levels, timing, and direct/ambient sound balance within the downmix process.
It will also demonstrate the latest update to Halo Upmix, the company's solution for upmixing stereo audio to 5.1/7.1/9.1 surround, which includes algorithmic improvements designed to enhance multichannel-to-multichannel mix and upmix adjustments.
The AMB Processor will also be on show. It enables post-production facilities to accelerate workflows significantly and reduce delivery times for a range of different tasks, with separate modules available for upmixing and loudness management. AMB also offers new features including threaded algorithm processing and multiple processing threads that are addressable for simultaneous parallel handling of files and queues.
ProCo Sound, an RHC Audio brand, will feature its HD-SDI Cable. The ProCo HD-SDI Cable is a 100 per cent sweep tested, low loss coax cable designed for professional broadcasters that need a high-performance and reliable SDI connection.
RTW is set to debut a 19” rackmount for its TM3 and TM3-Primus series of products. Also on display will be RTW's well-known TM7/TM9 TouchMonitors with upgraded firmware. The TM3 RackMount Solution comes in two versions that integrate easily with either the TM3 TouchMonitor or the TM3-Primus TouchMonitor by simply swapping out the necessary hardware. The TM3-2U is a mounting system for RTW's TM3 series products, including the TM3, TM3S, TM3-3G and TM3-3GS. With the appropriate mount, the TM3-Primus may also be used in this configuration. The TM3-Pri-2U is the exclusive rackmount for RTW's TM3-Primus, allowing mounting for the TM3-Primus into an appropriate mechanical environment for a customer installation.
Stage Tec presents AVATUS at NAB – a fully IP-based large mixing console with 21" multi-touch displays. Control elements and interfaces are connected through standard Ethernet. The console control surface and other elements communicate via IP networks, enabling remote production.
The control surface will initially consist of just three panel types. There are no central panels in the AVATUS mixing console concept. This enables multiple users to operate a console from different locations. The approach is supported by multi-touch displays, which provide access to all parameters and central functions. The mixing console interface can be split, since the displays can be relocated as required.
Studio Technologies introduces the new Model 371 Intercom Beltpack. The compact, lightweight unit combines the features offered by broadcast-style, 2-channel party-line (PL) intercom user devices with a single-channel listen output and a 4-pin male XLR headset interface connector. The flexibility of Dante and its inherent support of standard IP networks mean that multiple Model 371 units can be used in PL intercom applications with help from audio matrix units, such as the new Studio Technologies Model 5422 Dante Intercom Audio Engines. Model 371 units can also be directly interfaced with ports on compatible matrix intercom systems.
The Model 371 features professional audio quality that begins with superior microphone performance. Using a low-noise, wide dynamic-range microphone preamplifier and VCA-based dynamics controller (compressor) input, audio quality is preserved and the chance of signal overload is minimised. The resulting signal is routed to an analogue-to-digital conversion (ADC) section that supports a sampling rate of 48 kHz and a bit depth of 24.
Audio technology for productions of any scale – this is what Sennheiser and Neumann will showcase at their joint booth at NAB. The booth is divided into a number of areas to best showcase the breadth of solutions that Sennheiser and Neumann offer. The ‘Filmset’ area of the booth introduces visitors to the new Sennheiser Digital 6000 wireless system and the EK 6042 two-channel camera receiver, in addition to the Sennheiser MKH series shotgun microphones.
A typical audio desk has been recreated in the ‘OB van’ section. Neumann monitors, such as the KH 120 active studio monitor and the new KH 80 DSP nearfield studio monitor feature alongside Sennheiser’s 6000 series rack receivers. In ‘Radio World’ visitors can try out a selection of Neumann microphones including models from the renowned BCM line. Meanwhile, an AMBEO showcase illustrates the AMBEO VR Mic, together with immersive content created with it.
Wohler Technologies will be showcasing the AMP1-8-M dual input SDI 8-channel audio monitor, AMP1-2SDA 2-channel audio monitor and Audio over IP modules, including Dante and Ravenna /AES67, for its AMP2-16V Series audio monitors. The AMP1-8-M offers fast, intuitive operation for monitoring SDI audio and is ideal for in-studio or remote productions. It provides instantaneous selection and summing of any four SDI audio pairs. It features adjustable volume and balance controls, clear display of levels, and phase indications on bright 2.4-inch, LED-backlit LCD displays, with configurations that can be created, saved and recalled via an intuitive front panel interface. Users can monitor through built-in speakers, headphones or analogue outputs.
For those looking for essential monitoring capabilities in environments, including OB truck/vans and network/station facilities, the AMP1-2SDA offers Wohler's high-quality audio monitoring in a compact 1RU 2-channel version. It features adjustable volume and balance controls, clear display of levels and phase indications on bright displays. The unit can monitor via its built-in speakers or headphones with automatic speaker muting when headphones are connected. The unit offers several input options: 3G/HD/SD-SDI, analogue and AES3.
